Informations and abstract
Using dual-task paradigms, in which two subsequent stimuli were associated to an unspeeded and a speeded response, respectively, Jolicoeur and Dell'Acqua (1998) found that PRP effect could be generated by mental operations different from response selection. The present study, using the same paradigm, investigates a possible implication of the phonological rehearsal in the generation of the PRP effect. The obtained results, in line with the Central Interference theory, rule out the phonological rehearsal as explanation of the PRP. Moreover, they are consistent with the hypothesis that all the operations implemented from central mechanisms, such as consolidation or response selection, might underline the generations of the PRP effect.
